tion to grain heading machines, an obj-ectL being to provide means which may be supported bythe elevator of agfrain header1 for thepurpose of leveling the loaded grain-,1n the header bon or barge and thus `load the ksaid barge or -boX to its 1capacity without wasting the grain and at the same time 'dispensing 'with theservices of a man usually employed for this purpose.

Another object ofthe invention is the provision 'of a load level'er which'may be yieldingly and adjustably supported by the elevator so as to provide for variations of travel between the header and th'e hea-der boxes,the load 'leveler remaining in proper operative relationV to the sai'dbox `at lall times. ,v

A further object of the invention is vthe provision of means whereby the leveler may be operated from theoperating mechanism of the" header. f

Viith the above and other objects in View, the invention further'includes the following novel features and details of construction, to be hereinafter lmore fully described, illustrated in the accompanying drawings `and lpointed out in the appended claims.

In the drawings Figure lis aneleration showing aportion of the elevator of a grain heading'machine with .the invention secured thereto.

Figure v2 is afplan View of the same.

Figure 8 is an end view.

Figure -1 is a plan view of the rakes and frame showing the rakes in a diderent position from that of Fig. 2.

Figure 5 is a transverse section.

Figure 6 is an enlarged fragmentary elevation of one of the rakes.

Figure 7 is a'section" on the line 7-7 of Figure 6.

Figure 8 is an enlarged elevation partly broken away showing one of the parallel bars of the frame.

Figure 9 is a transverse section of the same.

Figure 10 is an enlarged section showing the 'connection between the 'crank shaft and one of the rakes. V

Referring to the drawings in 'detail wherein like characters of `reference denote corresponding parts, the reference character' 10 indicates a portion of the elevator of a grain heading machine to whichthe invention is shown as applied. i

The load leveler which constitutes the present invention comprises ja frame which includes longitudinally 'disposed Vspaced parallel bars 11 which 'areconnectedv at one `end by a transverse bar 12, the latter being preferably formed ofv angle iron and confnected to the said bars 11 as shown Lat 1'3, so that the bar 12 will voccupy a :plane'ab'ovethe bars 11. The opposite ends of the bars 11 are connected by a crank shaft`14 which forms one end of the frame. This shaft is mounted in bearings 15 which are connected to the bars -11 as shown at 16 so as to permit of pivotal movement of the frame upon the shaft 14 without binding.

Connected to the cranks 17 of thel shaft 14 as shown at'18 are leveling elements or rakes Y 19. `These rakes' 19 include teeth 2O and f when the said rakes `are moved longitudinally through their operative connection'with the shaft 14,-these tee-th will actto move the grain in the direction away from Vthe end of the' elevator 10. n

Theouter ends Iof therakes 19 are provided with extensions 21'whose extremities extend upward as at 22. The extensions 21 -of the rakes are positioned beneath the bar Y12, while extending through pivoted slides 23- carried byy the bar 12 are rods 23. These rods have one of their ends connected to the extremities 22 of. the rakes and their oppo- Ysite yends offset and connected vto the rakes solas to provide means for supporting said rakes for longitudinal movement.

Extending from the bar 12 substantially central of the length of said bar is a member 24; which is provided with an opening 25 and passing through this opening and" nected thereto one end of'a cable 31 which passes over a support 32 which extends from the frame of the elevator 10 and extends downward and rearward to within convenient reach of the operator to enable him to raise the loader from a loaded barge and let it down within an empty one.

The shaft 1flis mounted in bearings 33 which extend from bearing brackets 34: secured to the frame of the elevator 10, the said shaft being connected to a shaft by means of beveled pinions 36. The shaft 35 may be driven from any suitable part of the mechanism of the' heading machine for example, the pinion (not shown) on the lower roller of the elevator.

From the foregoing description and accompanying drawings it will be apparent that the invention provides a load leveler which is adapted to be positioned over the top of the header box or barge and operated from the mechanism of a grain heading machine to level the load within said box or barge, the manner of supporting the leveler acting to maintain the same in proper position for use.

The invention is susceptible of various changes in its form, proportions and minoil details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is -claimed is l. The combination with a grain header, of 'a load leveler comprising a frame, a plurality of pivoted and slidable reciprocatory leveling` elements mounted in said frame, means whereby said elements may be reciprocated and means for supporting thcleveler in position for use.

2. The combination with a grain header, of a load leveler comprising a frame, a crank shaft mounted for rotation in said frame, reciprocatory leveling elements operatively connected to said shaft and guided in said frame, bearing brackets extendingA from the grain header elevator and receiving said shaft to support the frame for vertical pivotal movement, means Connecting the frame and reciprocatory elements to the shaft to permit of horizontal swinging movement, means for yieldingly supporting the frame and means for operatively connecting the shaft to the header mecha nism for operating the reciprocatory elcments. Y

3. The combination with a grain header, of a load leveler comprising a frame, a crank shaft mounted for rotation in said frame, reciprocatory leveling elements operatively connected to said shaft and guided in said frame, bearing brackets extending from the grain header elevator and receiving said shaft to support the frame for vertical pivotal movement, means connecting the frame and reciprocatory elements to the shaft to permit of horizontal swinging movement, means including a horizontally disposed spring supported bar connected'to theload leveler frame for yieldingly supporting the latter and means for operatively connecting the shaft to the header mechanism for operating the reciprocatory ele-- ments.

4. The combination with a grain header, of a load leveler comprising a frame, a crank shaft mounted for rotation in said frame, reciproeatory leveling elements operatively connected to said shaft and guided in said frame, bearing brackets extending'from the grain header elevator and receiving said shaft to support the. frame for vertical pivotal movement,v means connecting the frame and reciprocatory elements to the shaft to permit of horizontal swingingl movement, a supporting bar, means including springs secured to the opposite ends of the bar for supporting the latter upon the frame ofthe header elevator, an armconnected to and extending laterally from the supporting bar, a sliding connection between the arm and frame, means secured to the outer end of the armrfor supporting the latter and means for operatively connecting the shaft to the header mechanism for operating the reciprocatory elements.
